Select one of the case studies below for your assignment. In your discussion, be sure to evaluate the presence and effects of alterations in the homeostatic state secondary to gender, genetic, ethnic, and temporal variables.

Case Study Assignment Requirements

1. Make sure all of the topics in the case study have been addressed.
2. Cite at least three references in your case study paper; this may include peer-reviewed journal articles, textbooks, or evidence-based practice websites to support the content.
3. All reference sources must be within 5 years.
4. Do not use sources such as Wikipedia or UpToDate as a reference.
5. Assignments must have at least four full pages of analytic content, double-spaced (the cover and reference pages do not count in the page count, but must be included with the assignment), and follow APA 7th edition format.

Case Study 3: Disorders of Ventilation and Gas Exchange

Emmanuel and his mother live in an urban community housing complex. The building is worn down and dirty from the urban dust, cockroaches, and mold. Emmanuel is 5 years of age and has suffered from asthma for the last 2 years. One evening, his mother poured him some milk and put him to bed. Shortly afterward, Emmanuel woke up wheezing and coughing. As he gasped for air, he became more and more anxious. His mother ran for his inhaler, but he was too upset and restless to use it. Emmanuel’s skin became moist with sweat, and as he began to tire, his wheezing became quieter. His mother called 911 and waited anxiously for the ambulance to arrive.

1. Emmanuel uses a corticosteroid inhaler for the management of his asthma. What is the mechanism of action of this drug? How is its action different from the ?₂-agonist inhalants?
2. Why does someone with severe asthma become physically fatigued during a prolonged attack? What are the physiologic events that occur during an attack?
3. One of the complications of respiratory fatigue is the development of hypercapnia. How does the body compensate for an increase in CO₂? What are the effects of hypercapnia on the central nervous system?
